Which of the following describes a load binder?

A load binder is a mechanism specifically designed to tighten and secure load restraints. It is an essential tool in ensuring that cargo is properly secured during transportation, preventing shifts that could lead to accidents or damage. Load binders typically work by applying mechanical advantage, enabling the user to exert considerable force to tighten the straps or chains that hold cargo in place. This is particularly important for larger loads or in scenarios where standard tensioning may not be sufficient.

The other options do not accurately reflect the function of a load binder. While a tool that ties cargo using manual effort could describe some securing methods, it lacks the specific functionality and mechanical advantages provided by a load binder. The suggestion that a load binder increases the weight of cargo is incorrect, as its purpose is to secure the load rather than alter its weight. Similarly, while there are straps used for securing light loads, this does not encompass the broader function and application of a load binder, which is suitable for a variety of load types and sizes.
